REGENERATIVE GAS-LAMP.

SPECIFICATION forming part of Letters Patent No. 350,438, dated October5, 1886.

Application filed September 5, 1884. Serial N0. 142.274. (No model.)

To all whom it may concern:

Be it known that I, CI-IARLEs'M. LUNGEEN, a citizen of the UnitedStates, and a resident of New York, in the county of New York and Stateof New York, have invented cert-aiu new and useful Improvements inRegenerative Gas- Lamps, of' which the following is a specification.

My invention relates to improvements in the Io construction ofregenerative gas-lamps of the general form heretofore patented to meJuly 3, 1882, and patented June 24, `1884, No. 300,879, and refers moreespecially to the arrangement and relation of the various parts of thesame. In the form of lamp referred to the distinguishing characteristicsare the flame plate or surface arranged within and above the flame, andover which the flame from the burner sweeps, in combination with theair-supply passages for the flame, heated by said flame or the heatedproducts of combustion. I have shown my present invention as embodied inone forni of' a lamp having these general characteristics, but at thesame time'it is to be understood that the features of noveltyhereinafter claimed are alike applicable, and are designed forapplication to other forms of such lamp. y

The lamp shown in the drawings, while being ofthe general formmentioned, is alsoshown as also embodying the feature of additionalairsupply to the body of the flame, as claimed in my prior application,No. 136,052, filed June 26, 1884.

In the accompanying drawings, Figure l shows a hanging lamp embodying myinvention, one half being shown in vertical section and the other halfin elevation. Fig. 2 shows a variation of one feature of the lamp invertical elevation. Fig. 3 shows in vertical section a form of thelamparranged as a stand or table lamp. Figs. 4 and 5 illustrate insection and plan a modification of construction. Fig. 6 shows a detailof construction.

G, Fig. l, indicates a gas supply pipe, from which depends an Argandburner, B, of any desired kind, connected to the pipe Gby av number ofseparate pipes, between which latter air enters to the interior of theburner.

5o The openings in the burner are formed vin its.

of the flame, which aids in sweeping the llame near the lower end. Theburner hangs in the interior of an air-shell, A, the lower portion ofwhich constitutes or has attached to it a v flame plate or director, A',preferably of re- 5 5 fleeting material, over the outer surface of whichthe flame is directed. A perforated disk, A, serves to admit a properproportion of' air to the inner side of the flame. .A portion of the airsupplied to the interior of the 5o shell A passes to the interior of theburner, and thence to the under side of the flame. Beneath the flame isa deflecting button or surface, substantially as shown in my priorPatent, No. 300,879. The airshell A is connected with a regenerator,shown here as placed above the shell and supporting the same. Air passesthrough this regenerator to the shell, and is supplied to both sides oftheilame,as indicated. Theregcneratorshown 7o is composed of the innerand outer concentric shells, r r, connected by separated hollowcross-tubes t, the air passing through said crosstubes, while theescaping products of combustion pass between them and heat the air. Thisapparatus might be formed of horizontal plates with verticalconnecting-tubes passing through them, so that the products ofcombustion would pass through the tubes and the air around them, asshown in vertical sec- 8o tion and plan in Figs. L,Land 5. D indicates ashell depending from the shell r, or otherwise supported, which servesto deflect the flame inward away from the inclosingglass and cause it topass around the upper edge of the llame-surface A. The lower ordeflecting edge of the deiieotor extends down to or nearly to the tip ofthe flame, so as to act positively in turning the iiame inward. Thisshell or detlector may belarger than the flame 9o plate or surface, asshown in Fig. 1, or may be of the same or nearly the same diameter, asshown in Fig. 2. In this latter case the tips of the flame are deflectedinward within the line of the circumference of the flame-plate. Theglobe E is hung from a holder, E', which may be removably attached tothe-outer shell, r. A number of fine openings in this holder admit aregulated amount of air to theoutside roo inward to the interior of theshell D and tov ard the upper end of the flame-surface,` thus promotingperfect combustion at the tips of the iiame. The regenerator is setwithin the shell F, the upper portion of which forms the flue for theescaping products of combustion passing to the chimney G. From the lowerend of shell F depends a perforated ring, F', through which the air t0supplythe flame passes, and by which it is broken up into a number ofsmall currents. rlhe ring F may be made removable, and be supported onthe shell F by means of a bayonet-joint, as shown at fj", Fig. 6, or inany other desired manner, and serve for the support ofthe shade S, asshown in the same gure.

In the table-lamp shown in Fig. 3 the burner is preferably made withoutan air-passage through it, the air to supply the under side of the flamenear the burner-tip being admitted tlnougha casing, II, surrounding thegaspipe G, by which the burner is supported,this pipe passing down intoan ordinary table-standard, the top portion of which is shown in thefigure. rlhe whole apparatus rests upon the rod B', rising from theburner. The top of said rod enters a socket in the tripod or frame atthe upper end of' the shell A. The opening in, the bottom of the globe Efits snugly around the tube H, and the diameter of the Argand burner issomewhat less than that of" the tube. rlhe whole apparatus, exceptingthe Argand burner and the base, may by this construction be lifted forthe purpose o1" lighting the burner or for removing the globe forcleaning.

A burner constructed as described yields a white steady light ot' lnuchgreater intensity than that given by ordinary gas-flames consuming thesame amount of gas.`

Vliat I claim as Iny invention is- 1. rlhe combination of aburner, allame plate or deflector arranged above the burnertip and in closeproximity to the burner, a second deflcctor independent of the outershell or casing of the lamp, above the first and around its upper part,with a space between the same and thefiame-plate, the said space formingan opening or passage for the escap ing products of combustion,substantially as specified.
